7 years ago package name: com.casimirlab.simpleDeadlines version: 3.2.1 Exception: java.lang.IllegalStateException: Fragment DeadlineListFragment{ad2ef970} not attached to Activity Category: Lifecycle Description: When doing time-consuming operation in background thread(e.g, AsyncTask), a new Fragment has been created in the meantime, and was detached to the Activity before the background thread finished. The code in UI thread(e.g.,onPostExecute) calls upon a detached Fragment, throwing such exception. Fix solution: 1: Cancel the background thread when pausing or stopping the Fragment 2: Use isAdded() to check whether the fragment is attached and then to getResources() from activity.
I'm looking forward to your reply.
